Abstract
The utility model discloses a synchronous control sensor for an artificial respirator, which is composed of a tubular cavity housing body, a temperature measuring resistor, a heat radiation resisting shielding cover, a semiconductor refrigerator and a radiator. The tubular cavity housing body is penetrated into the air delivery pipe of the artificial respirator and the pipe segment of the exhalation and air suction face shield of a patient. When expiratory air flow passes through the cavity of the tubular cavity housing body, the temperature measuring resistor collects the temperature signals of the expiratory air flow to be sent the control instrument of the artificial respirator, that is, the artificial respirator is in the state that the artificial respirator helps to exhale. After the air is finished to be exhaled, the temperature in the cavity of the tubular housing quickly drops to the temperature before the air is exhaled. Now, the temperature signals collected by the temperature measuring resistor are sent to the control instrument of the artificial respirator, that is, the suction aiding system of the artificial respirator is started.
Description
This utility model relates to a kind of Synchronization Control pick off of artificial respirator control device, particularly artificial respirator.
Existing artificial respirator mainly adopts the number of times of breathing according to patient's per minute to set this method of respirator per minute assisted respiartion number of times (GB11747-89 and YY0042-91 prescribed by standard be exactly this pattern) can't realize synchronous assisted respiartion for the uneven patient of respiratory rhythm, sometimes in addition cause when the patient gives off carbon dioxide since respirator asynchronous with the patient be not auxiliary exhalation, but back draught (respirator is in to help and inhales duty) has suppressed the carbon dioxide exhalation, increased the delay of intravital carbon dioxide, aggravated acidosic pathogenesis, even the even breathing rhythm and pace of moving things, this artificial respirator also is difficult to exhale with the patient and inhale beginning time duty Phase synchronization only, this just will inevitably influence and suck and the exhalation optimum efficiency, has influenced rehabilitation of patients.Existing artificial respirator also has the duty of exhaling Yu inhaling that adopts the method control artificial respirator of measuring the respiratory pressure difference, it is synchronous with patient respiratory that this method is made every effort to, it is asynchronous that but gaging pressure also exists the hysteresis of saturation time to cause, the patient respiratory that has is extremely faint and rapid, use gaging pressure just to be difficult to make and suck with exhalation pressure to reach breathing differential pressure pickup saturation value, pressure reduction control artificial respirator is breathed in measurement and patient respiratory also acquires a certain degree of difficulty synchronously.
The improved technique scheme that this utility model proposes at existing technical deficiency reaches Synchronization Control the pick off complete and artificial respirator that patient respiratory is synchronous in use.
This utility model is to realize like this, in the appendix of artificial respirator and pipeline section that the patient respiratory road links to each other, the air-flow temperature detecting resistance is set, utilize human body exhaled air flow temperature always with the human body body in temperature close, and the temperature of the gas that sucks when air-breathing is always close with ambient air temperature, both temperature difference together go to control the duty of artificial respirator as the signal source of gathering, the temperature signal that collects exhaled air flow removes to control artificial respirator and makes it to be in the state of exhaling that helps, the higher temperature blackout of exhaled air flow when the patient is air-breathing, artificial respiration's machine aided state of exhaling stops, the ambient temperature signal that temperature detecting resistance is gathered when air-breathing, control artificial respirator and be in the suction state that helps this moment, in order to overcome the ambient temperature instability, and other temperature signal in scratching, (ambient temperature and human body exhaled air flow isothermal sometimes) is installed in temperature detecting resistance the relative closure tubular type intracavity of temperature controllable, at the tubular type intracavity semiconductor cooler is installed also, utilize the cold of semiconductor cooler the tubular type cavity temperature to be controlled the temperature that is lower than the human body exhaled air flow, make it to keep the exhaled air flow and the air-breathing right temperature difference, for improving the precision of temperature detecting resistance acquired signal, prevent the influence of the cold emission of semiconductor cooler to temperature detecting resistance, a radiating radome of heat resistanceheat resistant (radome adopts the bright film glass of light-plated to make) radome is installed between the cold junction of temperature detecting resistance and semiconductor cooler should certain convection current air gap when mounted, make neither have between temperature detecting resistance and the semiconductor cooler cold, heat radiation influences but keeps heat convection with its ambient air.
Accompanying drawing is this utility model artificial respirator Synchronization Control sensor construction cutaway view;
Be described in further detail below in conjunction with accompanying drawing:
Realize good being connected for making this pick off with artificial respirator, this sensor housing is made into tubular type cavity shell (1) to be made it to seal in easily in the face shield pipeline section that the gas pipeline of artificial respirator contacts with the patient, temperature detecting resistance (2) is installed in the tube wall inboard of tubular type cavity shell (1), the lead (3) of temperature detecting resistance (2) is put tubular type cavity shell (1) outside, making it convenient is connected with the control instrument of artificial respirator, semiconductor cooler (5) is installed in the downside of tubular type cavity shell (1), cold junction is at intracavity, the hot junction is outside the chamber, the hot junction of radiator (6) and semiconductor cooler (2) contacts well that to make it heat dispersion good, heat resistanceheat resistant radiation shield (4) (radome (4) adopts the bright film glass of light-plated to manufacture) is installed between the cold junction of semiconductor cooler (2) and temperature detecting resistance (2), and radome (4) only covers the cold junction face of semiconductor cooler (5), but periphery should keep certain convection current air gap.The air communication of breathing out during use is crossed tubular type cavity shell (1) intracavity, the signal that temperature detecting resistance (2) was gathered with per 0.3 second sampling period sends to the control instrument of artificial respirator immediately, promptly start helping paging system that artificial respirator is in to help and exhaling duty of artificial respirator, after exhaled air flow finishes, because the temperature signal of exhaled air flow disappears, this moment, the temperature of tubular type intracavity mainly was subjected to the control of semiconductor cooler (5) cold, the temperature of housing (1) intracavity produces convection current rapidly, the temperature signal that temperature detecting resistance this moment (2) is gathered when being air-breathing, artificial respirator promptly transfer to and help the suction duty.Because the cold effect of set semiconductor cooler (5) has guaranteed to exhale and the temperature difference of inhaling biphase air-flow in the tubular type cavity shell (1), the air-flow of exhaling and inhaling always will be by the tract of tubular type cavity shell (1) relative closure, exhaling can be not influenced by ambient temperature with the temperature gap of inhaling biphase air-flow, has guaranteed that artificial respirator and patient respiratory are synchronous.
